Area Forecast Discussion National Weather Service San Diego CA 335 AM PST Sun Dec 8 2019

SYNOPSIS. Moist southwest flow aloft will bring periods of light rain and high elevation snowfall today. Showers will end late tonight after a cold front moves south across the region. Weak high pressure aloft will bring dry weather Monday and Tuesday. Another ridge of high pressure will bring even warmer days Thursday and Friday.

DISCUSSION. FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE . SAN DIEGO . WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES .

Six-hour rain totals ending at 3 AM today ranged from the low end of 0.01"-0.05" in the coastal and valley zones to the higher values of 0.10"-0.25" on the west and southwest facing mountain slopes. This pattern will continue through the morning with a steady stream of tropical moisture moving in from the southwest.

This afternoon the PWATs that were near 1.45" early this morning will fall to around 1.00" as the tropical moisture plume is forced south by a longwave trough moving in from the north. The precipitation will become more convective in nature as shortwaves round the base of the trough this afternoon/evening. Cold air aloft and PVA will destabilize the atmosphere with scattered light to moderate showers possible just about anywhere. Southwest onshore winds ahead of the trough will be a little stronger this afternoon/evening which should continue to enhance precipitation amounts on the west/southwest facing mountain slopes.

Showers will taper off tonight as the trough axis moves east. Snow levels near 7,500 feet this morning will steadily fall during the day to around 6000 feet tonight with a few inches of snow in the higher mountains.

Monday through Friday . A ridge building over the West Coast Tuesday gets flattened Wednesday by a weak shortwave, but the ridge then morphs into an elongated east-west oriented 592 dm high over the eastern Pacific. This pattern will bring dry, warmer weather Thursday and Friday. Ensemble blends show the ridge weakening for minor cooling Saturday and Sunday but temperatures will still be at or above normal.

AVIATION. 081010Z . Coasts/Valleys . BKN-OVC cigs with bases 1500-2500 ft MSL, locally 600-800 ft MSL at times, through 20Z. After 20Z BKN-OVC cigs 2500-4000 ft MSL, locally lower in areas of -RA.

West winds with gusts to 35 kt over the mountains will bring weak-moderate up/downdrafts and LLWS over and east of the mtns 12Z Sun-06Z Mon.

Deserts . Isolated -RA possible through Sun with BKN-OVC cigs 4000- 7000 ft MSL. Local vis 3-5 miles will be possible in -RA through Sun. Mid-high level clouds expected to clear by Sun evening.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
